The present invention relates to a sheet conveying apparatus, and more particularly, to a sheet conveying apparatus capable of conveying a plate member of various shapes more stably even with a simpler structure.

There are various reasons for transporting sheet material. For example, in order to continuously cut or bend a plate such as a cutting blade, the plate must be continuously supplied to the cutting device or the bending device. As described above, in order to continuously transfer the plate, a structure in which the roller is brought into contact with one surface of the plate and the plate is transferred by the rotation of the roller has been conventionally used. However, when using the roller in this way, there is a problem that the roller marks remain on one surface of the plate. In addition, even if a different structure is used without using a roller, there is a problem in that the structure is very unstable and the sheet material cannot be stably transferred. In addition, the conventional sheet conveying apparatus has a problem that there is a limitation in the shape of the sheet capable of conveying. That is, when the protrusion extending from one surface of the plate in a direction perpendicular to the side of the plate is formed on the side of the plate, the contact between the roller and the plate is poor, there is a problem that the plate is not transferred stably.

Therefore, the present invention has been made to solve the above problems, the object of the present invention is to not only stably transport a plate of various shapes with a simpler structure, but also does not leave roller marks on the plate during the transfer of the plate It is to provide a sheet conveying device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments. For reference, in the present description, the same numbers refer to substantially the same elements, and may be described by quoting contents described in other drawings under these rules. And it can be omitted that it is determined or repeated to those skilled in the art to which the present invention pertains.

Example 1

1 is a perspective view showing a sheet conveying apparatus according to a first embodiment of the present invention, Figure 2 is a perspective view showing a state in which the plate is loaded in the sheet conveying apparatus of FIG. As shown in FIGS. 1 and 2, the sheet conveying apparatus according to the present embodiment includes a guide member 110, a first moving member 130, and a second moving member 150. For reference, in the present specification, the plate means a material mainly made of a metal material and formed in a plate shape. Such a plate is usually formed in a strip shape (strip shape) or the like to allow continuous conveyance through the plate conveying device.

The guide member 110 is provided in a direction parallel to the conveying direction (t) of the plate material refers to a configuration for guiding the first moving member 130 and the second moving member 150 to be described later in a predetermined direction. The guide member 110 is preferably configured to convert the rotational movement of the guide member 110 into a linear movement of the first moving member and the second moving member 150. This configuration is because the overall structure of the sheet conveying apparatus can be simplified more. For example, the guide member 110 according to the present embodiment is formed in a direction opposite to the first screw portion 112 having a spiral groove formed in a predetermined direction and the spiral groove of the first screw portion 112. It may include a second screw portion 116 having a helical groove to be. That is, the guide member 110 according to the present embodiment may be present in the same member with the thread formed in the form similar to the right screw and the thread formed in the form similar to the left screw.

And correspondingly, the first moving member 130 includes a first base portion 132 is formed in the helical groove corresponding to the helical groove of the first screw portion 112 to move in engagement with the first screw portion 112. In the same manner, the second moving member 150 may include a second base portion 152 which is formed with a spiral groove corresponding to the spiral groove of the second screw portion 116 and is engaged with the second screw portion 116. ) May be included. Further, steel balls may be inserted between the spiral grooves of the screw portions 112 and 116 and the spiral grooves of the base portions 132 and 152 to be rolled. In this configuration, the first moving member 130 and the second moving member 150 can be moved in different directions by only rotating one guide member 110 in one direction. For reference, the configuration of the guide member and the moving member is not limited to the above configuration, but if configured in the form of a ball screw as described above, the moving member can be moved along the guide member more stably.

The first moving member 130 and the second moving member 150 move in different directions along one guide member 110 as described above. That is, when the first moving member 130 moves from the first time point p1 to the first end point p2, the second moving member 150 moves from the second time point p3 to the second end point p4. do. This movement is repeated between the starting points p1 and p3 and the ending points p2 and p4. For this movement, the guide member 110 rotates in one direction to move the moving members 130 and 150 from the starting points p1 and p3 to the end points p2 and p4, and then rotates in the opposite direction to move the moving members. (130, 150) is moved from the end points (p2, p4) to the time points (p1, p3). For the rotation, the plate conveying apparatus according to the present embodiment is provided at one end of the guide member 110 and rotates together with the guide member 110, and transmits a rotational force to the connecting portion 172 to guide the member ( The driving unit 180 for rotating the 110 in a constant direction and the opposite direction is provided.

For example, as illustrated in FIGS. 1 and 2, the connection part 172 may be configured in the form of a pulley. That is, as shown in FIGS. 1 and 2, pulleys 182 and 172 are installed at one end of the driving unit 180 and the one end of the guide member 110 which are usually constituted by a motor or the like, and then the pulleys 182 and 172 are provided. When connecting between the belts 192, the rotational force generated by the driving unit 180 may be transmitted to the guide member 110. However, the configuration of the connection unit is not limited to the above configuration, and the connection unit and the driving unit may be connected by gear coupling or the like. The connection part may be provided separately from the guide member and connected to the guide member, or may be integrally formed with the guide member.

On the other hand, the moving members 130 and 150 have a first moving member because the clamping part 136 and the second moving member have a clamping part having the same configuration as that of the first moving member in order to selectively clamp the plate M. Reference numerals only). Here, optional means that the plate M may or may not be clamped under the control of the controller. For this clamping, the clamping part 136 moves to the plate M from the opposite side of the support 138 between the support 138 supporting one surface of the plate M and the plate M between the plate M. It may include a contact portion 139 in contact with the other surface of the. That is, when the contact portion 139 moves toward the plate M in contact with the other surface of the plate M in a state in which one surface of the plate M is supported by the support 138, the plate M is clamped. 136). When not clamping the plate (M), the contact portion 139 may be moved in a direction away from the plate (M). The driving part 194 may be provided in the clamping part 136 to move the contact part 139. That is, when a rotational force is generated in a predetermined direction, the contact portion 139 moves toward the plate M, and when a rotational force is generated in the opposite direction, the driving unit 194 moves the contact portion 139 in a direction away from the plate M. Can be configured.

And it is preferable that the contact part 139 is movable in the direction perpendicular | vertical to the conveyance direction t of a board | plate material, ie, the height direction h of a board | plate material. This is because, when a part of the plate M is formed along the longitudinal direction, and the contact between the plate M and the contact 139 becomes poor, the contact part 139 is moved in the height direction (Fig. 1, to avoid the protrusion). It is because it is preferable to make the contact between the board | plate material M and the contact part 139 favorable by moving to the up-down direction based on 2. Moreover, in order for the contact part 139 to contact the board | substrate M more stably, it is preferable to have the form in which the contact part 139 extends in the longitudinal direction (the conveyance direction of a board | plate material) of a board | plate material. Since the protrusions are generally formed along the longitudinal direction of the plate, the contact portion 139 has a form extending in the longitudinal direction of the plate rather than having the form extending in the height direction h of the plate. 139) is more preferable in terms of good contact between them.

For reference, the specification describes that the contact portion 139 moves in the height direction h of the plate, but this description does not mean the movement of only the contact portion. That is, depending on how the moving member according to the present embodiment is designed, only the contact portion 139 may move in the height direction h of the plate, and the contact portion 139 moves in the height direction h of the plate together with other configurations. You can also move. The clamping part described above may be provided separately from the base part described above, or in some cases, may be formed integrally with each other. In addition, the above-described support part 138 may be configured to include a generally flat portion so as to correspond to one surface of the plate (M), but when one surface of the plate (M) is formed with a certain curved surface or the like includes a curved portion to correspond to this. It can be configured to. As a result, the support portion 138 is preferably replaceable with a shape corresponding to the shape of one surface of the plate (M).

The operation of the sheet conveying apparatus according to the present embodiment having the above configuration will be described in detail. First, the board M is mounted on the board conveying apparatus (a conventional structure such as guide means may be further provided for this mounting). Then, the contact portion 139 of the clamping portion 136 is appropriately moved in the height direction h of the plate so that the contact between the plate member M and the contact portion 139 is made better. Thereafter, the contact part 139 is moved toward the plate M to rotate the guide member 110 in a predetermined direction while the plate M is clamped, thereby moving the first moving member 130 at the first time point p1. It moves to the 1st end point p2, ie, the feed direction t of a board | plate material. At this time, the second moving member 150 moves to the second end point p4 at the second time point p3 in the state in which the plate M is not clamped, that is, in a direction opposite to the conveying direction t of the plate. For reference, the lower surface of the plate M may be supported by a bearing part (not shown) so that the plate M may be more smoothly transferred by the moving members 130 and 150. As such, when the bearing part supporting the lower surface of the plate M is provided, the plate M may be smoothly transferred by the rotation of the bearing part (bearing).

As described above, since the first screw portion 112 and the second screw portion 116 of the guide member 110 are formed in opposite directions to each other, even if the guide member 110 rotates in one direction, The first moving member 130 and the second moving member 150 may move in opposite directions. When the first moving member 130 moves to the first end point p2 by the movement, the guide member 110 is rotated in the opposite direction to move the first moving member 130 back to the first time point p1. In addition, the second moving member 150 is also moved to the second time point p3. In this case, the first moving member 130 moves in a state where the plate M is not clamped, whereas the second moving member 150 moves in the plate conveying direction t, so that the first moving member 130 moves in a clamped state. do.

As such, when the first moving member 130 and the second moving member 150 are clamped only when the first moving member 130 moves in the conveying direction t of the sheet while reciprocating between the starting point and the end point, the sheet M is transferred. Can continue to be conveyed in the direction. As described above, the plate conveying apparatus according to the present embodiment can not only convey a plate of various shapes such as having a protrusion in a certain direction with a simpler structure, but also roller marks on the plate during conveyance of the plate because no rollers are used. The advantage is that it does not remain. For reference, the rotation of the guide member, the movement of the contact unit, and the like during the above driving may be automatically realized through a control unit.

Example 2

3 to 5 is a perspective view showing a sheet conveying apparatus according to a second embodiment of the present invention, Figures 6 to 8 is a perspective view showing a state in which the sheet material is loaded in the sheet conveying apparatus of FIGS. As shown in FIG. 3 and the like, the sheet conveying apparatus according to the present embodiment basically has the same configuration as the sheet conveying apparatus according to the first embodiment. However, the sheet conveying apparatus according to the present embodiment is different from the sheet conveying apparatus according to the first embodiment in that the guide member includes a first sub guide member and a second sub guide member. For reference, the same (or equivalent) reference numerals are given to the same (or equivalent) parts as the above-described configuration, and detailed description thereof will be omitted.

Referring to the sheet conveying apparatus according to the present embodiment based on the above-described difference, the guide member according to the present embodiment is a first sub-guide member 210 and the second sub-guide member 220 spaced in parallel to each other Include. The first moving member 130 moves along the first sub guide member 210, and the second moving member 150 moves along the second sub guide member 220. The guide member according to the first embodiment has a long length because two moving members must move within one member, whereas the guide member according to the present embodiment has two moving members within two sub guide members. The length is relatively shorter because they move separately.

That is, the sheet conveying apparatus according to the present embodiment is shorter in length than the sheet conveying apparatus according to the first embodiment. In addition, the first starting point p1 of the first moving member 130 corresponds to the second end point p4 of the second moving member 150, and the first end point p2 of the first moving member 130 is formed by the first moving point 130. When it corresponds to the 2nd viewpoint p3 of the 2 moving member 150, the length of a board | plate material conveying apparatus can be made shorter. In other words, as shown in FIG. 3, when the first start point p1, the first end point p2, the second time point p3, and the second end point p4 are sequentially connected to form a rectangle, The sheet conveying device can be the shortest.

Meanwhile, the first sub guide member 210 includes a first screw shaft 212 in which a spiral groove is formed, and the second sub guide member 220 also includes a second screw shaft 222 in which a spiral groove is formed. can do. At this time, the helical groove of the first screw shaft 212 and the helical groove of the second screw shaft 222 may be formed in the same direction or may be formed in the opposite direction depending on the form of the drive unit. For example, if the first screw shaft and the second screw shaft have helical grooves formed in the same direction, each subguide member is provided with a respective driving portion, and then the first screw shaft and the first screw shaft are opposite to each other. The first moving member 130 and the second moving member 150 may be moved in opposite directions by rotating in the direction.

However, it is preferable in view of the simplification of the device that the first screw shaft and the second screw shaft have spiral grooves formed in opposite directions to each other. If the first screw shaft 212 and the second screw shaft 222 has a spiral groove formed in the opposite direction to each other, as shown in Figure 3, etc., the first sub guide member 210 and the second sub guide This is because the first moving member 130 and the second moving member 150 can be moved in opposite directions with only one driving unit 280 which rotates the member 220 in the same direction. As such, the plate conveying apparatus according to the present exemplary embodiment further includes two connecting parts 272 and 274 to rotate the two sub guide members 210 and 220 in the same direction using only one driving part 280. As a result, one or more driving units may be provided, but it is preferable to drive the screw shaft with only one driving unit as described above.

The first connecting portion 272 is connected to one end of the first screw shaft 212 and rotates together with the first screw shaft 212, and the second connecting portion 274 corresponds to the first connecting portion 272. It is connected to one end of the two screw shaft 222 is configured to rotate with the second screw shaft 222. As such, when the first connection part 272 and the second connection part 274 are positioned on the same side surface, the driving unit 280 may also be positioned on the same side surface, and thus the two connection portions 272, The two sub guide members 210 and 220 may be rotated in the same direction through 274. This connection portion may also be configured in a pulley form similarly to the connection portion of the first embodiment.

On the other hand, the movable member according to the present embodiment may have a base portion and a clamping portion similar to the movable member according to the first embodiment described above. That is, the first moving member 130 includes a first base portion formed with a spiral groove corresponding to the spiral groove of the first screw shaft 212 and moving in a predetermined direction according to the rotation of the first screw shaft 212. The second movable member 150 may also have a spiral groove corresponding to the spiral groove of the second screw shaft 222 and move in a direction opposite to the first base portion as the second screw shaft 222 rotates. It may include a second base portion. In addition, the above-described clamping part may be connected or integrally coupled to the base part.

As described above, the present invention has been described with reference to preferred embodiments of the present invention, but a person of ordinary skill in the art does not depart from the spirit and scope of the present invention as set forth in the claims below.
